EDWARD R. MONROE, OF BAY CITY, MICHIGAN.

PAPEBr-TUBE-MAKING MACHINE.

Application filed April 16,

1' all whomit may concern:

Be it known that I, EDWARD R. MONROE, a citizen of the United Statesof America, residing at Bay City. in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Paper-Tube-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to paper tube-male i'ng machines, and its objects are to provide a machine of that character improved in various respects: also to provide such a machine which shall contain, in various combi nations, already-existing or my newly-invented parts and devices of such nachines :all as hereinafter appearing; and in general, to provide such a machine, and such parts and devices thereof, which shall be simple and economical in construction and easy and effective in operation.- These objects are attained by, and my invention finds a preferable embodiment in. the structure hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a side elevation of my paper tube-making machine Fig. .2 is a transverse vertical section thereof on line of Fig. l Fig. I) is a plan view ofthe same; Fig. 4 is a detail view in perspective of the tuberolling members and connected parts, certain parts being broken away; Fig. i) is alike view of portions of the same partially in section on the line 3 y Fig. (5 is a detail view in vertical section of parts of the tube- (li.--'charging devices, with portions broken away; Fig. 7 is a diagrammatic view, in a transaxial plane, of certain driving gears of my machine; Fig. 8 is a detail view in perspective of a portion of the tube-rolling shaft; Fig. 9 is a like view of the end of afinished tube; Fig. 10 is a like view of a retaining member for the paper tube-rolling pipe; and, Fig. 11 is a like View of a ratchet operating in connection with the feed-driving rack 29 and its gear 31.

()n the main frame 1 is carried by suitable supports 5 and 6. a table comprising end portions 2 and 3 and a removable inter- Specification of Letters Patent.

mediate portion 4, the support 6' being adjustable on the frame as by a bolt 100 so that, when it is desired to form a paper tube of more or less paper, a wider or narrower table portion t may be inserted into the machine, the end portion 3 being movable to the left or to the right of Fig. 1 to accommodate such intermediate portion and being then clamped on the frame by said bolt.

A roll of paper 9, turning on a shaft 8 carried by a suitable bracket 7, is unwound by the feeding rolls 13 and 14'c0nnected by gears 32 and 33 between which the paper passes after being properly tautened by a suitable tension roll 10 whose journals 11 are carried by arms 12 pivoted on the frame. After being trimmed to a true transverse edge by manual operation of the knife 15, the paper is fed by the feed rolls (toward the right in Fig. l) driven by suitable means, such as a belt (not shown) engaging the pulley 16 on the driving shaft 17 which carries a mutilated gear 18, having teeth to mesh with the gear 21 on the shaft 22 which carries a disk provided with a wrist pin and its anti-friction roller which, moving in a longitudinal slot, in the arm 25 pivot'ed at 26 and thus reciprocates the rod 28 adjustably pivoted at 27 to the arm, and also pivoted to a rack 29. This rack reciprocates in a bearing block 30 and meshes with a pinion 31 on the shaft of the feeding .roll 1 f, thus rotating said roll to feed the paper. The mechanism is adjusted so as to rotate the feeding rolls a sufiicient number of revolutions to feed the paper under the knife 15, over the table 2, 3, and 4: and between guides 35, to the tube-rolling members; Suitable pawls 101 are provided in the pinion 31 (see Fig. 11) engaging a ratchet in the shaft 34 to permit the upward or return movement of the rack bar without rotating the feeding roll backward.

A cam disk 38 carried by the driving shaft 17 is so adjusted thereon that, as soon as the paper is fed beyond a horizontal transversely-arranged glue pipe 37 adjustable in brackets 36 somewhat more than the length of paper required to make one turn of the paper-tube, the plunger 39 is moved by said cam to open a suitable valve &0, thusv per mitting the glue under pressure to flow from a pipe 4-0 (connected to a supply source not shown) and in a spray onto the paper for nearly its remaining length necessary to form the paper tube; whereupon the cam permits the valve L0 to close under the pressure of the spring 101%. Thepaper is thus coated with glue, and its forward edge guided by means of roller 7st and fingers 73 on the edge of the table 3 is fed into the lon-' gitudinal slot i3 through the wall of the tube-forming pipe -12 and also into the registering longitudinal groove in the 00- operating tube-forming shaft 14 having a limited relative rotatire movement inside the pipe and supported in bearings 46 and 4.7 at one end and on the movable bearing 70* at the other end. The teeth of the gear 18 having now passed out of mesh with the gear 21, and before they are carried into mesh with the gear 15) the cam 50 carried by the driving shaft 14 is turned to a position which allows the cam lever 51 to rise under tension of the spring 88, a connecting rod 53 being pivoted to the cam lever and to a lever 103 fixed on a rock shaft 54, whereby said lever withdraws the wedge 52 from its previous position between the arm 56, fixed on the shaft it and the arm 55 fixed on the pipe as the wedge is thus withdrawn the spring 57 draws these arms toward each other, thus throwing the slot 43 and groove 4:?) out of their registration and clamping the end of the paper between the shaft 44: and pipe and swings the roller 86 against the pipe 42, such parts now occupying the position shown in Fig. 5.

A cam disk 85 carried by the driving shaft- 17 moves the cam lever 82 pivoted at 72 downwardly, which through the connecting rodSil forces downwardly and against the pressure of a spring 80 the bar 79 reciprocable in a bearing block 10L adjustable on the frame in any convenient manner: This bar carrics'thc transversely-arrangcd horizontal bar 77 and its knife 15, which by this movement severs from the roll the length of paper required for one tube. Small punches 78 may be carried by the bar 77 and sufficiently in advance of such knife to punch suitable devicr-s. as the name of the owner, etc, through the part of the paper which is to form the outside turn of the tube.

The teeth of the gear 18 being now carried into mesh with the gear 19 on the shaft 20, the gear 49 on said shaft rotates the gear 48 on the shaft 44-, whereby the length of paper is wound around the pipe 42 and. being pressed by the roller 86 carried by arms 87 on the rock shaft 54, the paper tube is formed around the pipe 42. This done, the teeth of the gear 18 now pass into mesh with the gear 21 on the shaft '22 which shaft carries a bevel gear 59 meshing with a gear 60 on a. shaft 61 journaled in a bracket 62 and carrying a crank wheel 63 connected by a rod 65 to a bell-crank lever 64:, carrying a segmental. gear 58 meshing with a pinion 66 on. the shaft 6? journaled in a bracket 68. A

. fcar69 on this shaft meshes with a rack bar T0 slidable horizontally in guides 71 (see Fig. 6). This rack bar carries an arm encircling the pipe l; and a conical bearing 70 fitting into and supporting the spindle it during the tube-rolling operation, and carried away from the same when the tube is removed as hereinafter described. T his rack 70 is moved outwardly (to the lefthand in Fig. 2) by the above described movement of the segmental gear 58 and pushes the completed paper tube oi? the pipe and as the gear '21 makes one revolution the rack has re turned to its orig nal position, and during this revolution of said gear 21 the paper has been fed forward to the position for rolling another tube.

The pipe 42 is retained in place while the paper tube is being removed therefrom, by a. suitable retaining member 90 (shown in l igs. 4 and 10) detachably fastened to the shaft 4-4- by a collar 56 and having an overhanging portion as shown adapted to engage and hold the pipe 4'2 against longitudinal movement only. Such pipes 42 of various external diameters may be provided. all however, being adapted to fit internally around the shaft -14, and their inner ends being turned down to a uniform size, any one may be attached to mv machine by the retaining member 90: paper tubes of different diametcrs may thus be formed. lVhen the length of paper to make a paper tube is to be greater or less. the bearing block 10-r and support 6 may be moved along the frame to a corresponding adjustmentby any convcnicnt means.
